It never fails to amaze me how dulling of the grinder burrs is so insidious. I just replaced my Mazzer mini burrs. I replaced them only because I noticed that it seemed to be taking it longer to grind also the grind I use for my espresso was working for my Vac Pot. I neatly packed up the old burrs half convinced that they probably had 25 to 50. percent life left in them . They are less than 3 years old.They have probably only about 150 lbs of coffee through them. At any rate I just pulled a shot with coffee ground with the new burrs. I can't believe how much the shot improved. I guess i can go throw out the old burrs. Lesson learned if in doubt change the burrs anyway.

Funny you should mention that, Barry. I have been pulling my hair out trying to dial in sweet shots from my Andreja; I have re-run the pre-flushing cycles using the Scace Thermofilter and dialed the pressure down to 9.5 bar; using a 'neked' portafilter, have worked toward a perfect pull in time and volume...still bitter and full of sediment. I use Monkey Blend roasted to FC+/Vienna in a HotTop. Even my milk based drinks are stinky. I am now thinking the burrs on my Rocky are just about shot and the lack of uniformity in the grind might be the problema. Thanks for the 'light bulb'; I'm placing an order for new burrs NOW! |
Said it many times before will say it again. For Rocky grinding primarily for 'spro highly suggest replacing burrs every 75# max' to maintain quality grind. Whether that is your shot problem or not can't say with 100% surety though.

Get a new set of screws for the Rocky as well.

Not a bad piece of advice. However for the record I've changed the burrs on my Rocky 5 times without replacing burr carrier screws once. The key is to use ample, boo-koo, serious, whole bunches and gobs of downward pressure while breaking the screws loose to avoid stripping the head. Also imperative to use a properly fitting screwdriver that itself is not stripped.

Some Lock-Eze goes a long way too. The Rocky carrier is Brass so extra care with any pressure is in order.

There was a screw that wasn't hard to get at, straight shot up to it under the dash, but I couldn't get it loose. I thought I was going to have to drill it. But bought a smaller (correct fit), new tip for my screwdriver and it walked right out. Amazing. I don't doubt a bit that a new screwdriver tip of the right size (apparently it is fairly common to have trouble due to using too large a screwdriver tip) is key to changing burrs in grinders as well.

Don't just get screws, Get fillister head screws- grade 8 if you can find them, and a brand new driver that fits exactly. Socket head screws would be good, too, and get a new exclusive use hex wrench for them. Cheers, Mabuhay -RayO, aka Opa!

In the early seventies I was having trouble removing the cross headed screws on some Japanese motorcycles. A hand impact driver fitted with the correct bit did the trick without damage every time. (The hand impact driver is hit with a hammer so that it twists and pushes simultaneously). I now own two of them and can't find either one. That and Kroil.
